Oil consumption for a chainsaw per hour. Merged containers

Chain oil consumption

At least some two.stroke chatefering engine works on the consistency of gasoline with oil, respectively, on the property and the correct consistency of these components, it depends on how long it will last. Also in the chainsaws, the tire and the chain, and the quality of the lubricant is not the last factor affecting the duration of the use of these parts of the chainsaw. In this article we will talk about the oils that StiHL produces and advises for use not only on the chainsaws of its own production.

STIHL grease for two.stroke engines

STIHL engineers develop oils that are normally suitable for all two.stroke engines installed on chainsaws and trimmers for STIHL grass and not only. The line of lubricants for the two.stroke engines STIHL contains several product options:

STIHL HP is a lubricant for a chainsaw, designed taking into account large property requirements and was created to lubricate the internal parts of the motor when it operate. It is made on the mineral base and is characterized by good combustion indicators (it has a small level of excretion of harmful substances during combustion).

The original Stihl HP has a reddish color and is sold in Stihl proprietary packaging.

It is supplied in several variants of packing, the most popular of which is a bottle of one liter with an integrated dispenser. You can also meet Stihl HP in cans of 5, 10 and 50 5 liters.

consumption, chainsaw, hour

The smallest packing of Stihl HP, which is comfortable to use in cases where you need to prepare only one liter of fuel consistency, is a twenty.gram plastic bottle.

Also, the company produces 100 gram bottles of STIHL HP, which can be used to manufacture 5 liters. fuel consistency.

According to the advice of the manufacturer, STIHL HP can be used to make a consistency for all two.stroke engines.

The shelf life, subject to storage in a closed container, is 4 years.

What is the oil consumption for the lubrication of the chain of the chainsaw should be in relation to the consumption of gasoline?

The chainsaws are certainly different (models, power) and the oil consumption for lubrication of the chain is clearly registered in the instructions for a particular chainsaw. But most often a tank (tank) of chain oil goes to the fuel mixture tank.

That is, they developed a fuel mixture, then a new gas station and chain oil, including.

Suppose (the volume of the tank for the fuel mixture in different chainsaws, different) saw with a tank (fuel mixture) by 0.4 liters, consumption of chain oil 200 grams, that is, 0.2 liters per volume of the fuel mixture.

Of course, many such consumption is surprising (when buying a chainsaw, users simply do not suggest that the consumption of chain oil is so huge), you need this to lubricate the chain

It is not cheap, so there are only 2 options, or reduce the consumption of chain oil by adjustment, of course this is a violation of the recommendation of the manufacturer, but the consumption of the oil tank (chain) per two fuel tank is quite a working option.

Or fill the tank for lubricating the chain with other less expensive oil.

Some even use the development, though cleaned, or car oil, or transmission.

Of course, the chainsaws are more mobile (it is possible to work far from the electricity source) and more powerful power saws, but if all the work is carried out near the house, then the electric saw is much cheaper in operation (power plants can also be of different capacities).

Oil for lubrication of the chain and it is used in it, but there is no fuel mixture (gasoline oil), which is also not cheap.

Oil for lubrication of the chain of chainsaw. Review, lubrication process, reviews

Chain chainsaw is a rather complicated device that requires constant care and maintenance. The owner of the tool can perform part of these works independently, in case of complex malfunctions, we advise you to contact experienced mechanics.

The performance of chain benzo and electric saws depends on many circumstances. The power of the engine, the experience of the operator, the quality of the saw headset and the fuel and lubricants should be taken into account. In addition, modern chainsaws are equipped with automatic lubricant chain, without which it is now difficult to imagine even the cheapest tool.

What is the system of automatic lubrication of the chain, how it functions and what its serviceability depends on, we will tell in our material. We pay special attention to the problem of choosing oil for lubrication, we will introduce the recommendations of leading manufacturers in this matter.

Mineral or synthetic oil. which is better to add to gasoline

Two.stroke oils can be mineral or synthetic. As in the case of a car, synthetics here always cost more than a mineral water. Its most important advantage is that when using a chainsaw inside the cylinder, soot is not formed. This extends its service life. Thus, if you want a saw to serve as much as possible, pour synthetics.

Husqvarna power saw #viral #chainsaw #race

True, it is worth noting that if you have already used a mineral water for a long time (at least 100 mothers), then you can not use synthetics. This is due to the fact that synthetic oil, possessing cleansing properties, will wash off a layer of soil accumulated on them from the cylinder walls, and its dumped pieces can lead to damage. Therefore, if you have been using mineral water for a long time, then use it.

Comparative review of the motor oils Stihl

The branded oils of the same purpose in composition and characteristics practically do not differ, therefore, as a small review, you can compare the characteristics of three motor oils of the popular Stihl brand.

  • Stihl HP motor oil is the optimal option and working characteristics. Its recipe is focused on the use of semi.professional and professional class in productive saws. When combustion, the composition does not form soot and toxic compounds, does not destroy the gaskets, has increased resistance to large and extreme loads.
  • STIHL HP Super is a classic low.zero semi.synthetics that meets user needs with increased requirements.
  • Stihl HP Ultra. pure synthetics, oil in its capabilities can be considered universal, as it has special resistance to temperature and loading effects. Great material for use in powerful ICE of professional chainsaw technology.

Manufacturers, on the contrary, set consumption per unit engine power. In order to calculate the fuel consumption for one moto work, it is necessary to use the corresponding formula: (NTG%)/p. To determine and accurately calculating the formula, it is necessary to clearly know all the necessary components:

  • N is the power of the engine measured in kW;
  • t is the fuel consumption time, that is, 1 hour;
  • G-the specific consumption of the fuel of the machine, g/kWh;
  • %. percentage of car loading during operation;
  • P. fuel density.

Often they choose unhealthy gasoline, since it complies to a large extent established standards. The exact brand is indicated by the manufacturer of the chainsaw in the operating instructions. That is why problems with the choice of the most suitable composition should not arise. The use of fuel, which does not fit the main parameters, leads to the problems below:

  • Power indicator may significantly decrease.
  • Power can jump in a fairly large range.
  • Engine overheating will begin when the recommended octane number exceeds. Too high temperature can lead to the fact that the plasticity of the material will increase, and the design will fail under the influence of high load.

In addition, it is strictly forbidden to mix the gasoline mixture with other dubious compositions.

General provisions

The collection “The norms for the consumption of fuels and lubricants for mechanized works performed in forestry” included individual consumption standards for combustible materials for the main types of work: forest cultural (work in nurseries, stumps on cutting with tractor units, continuous treatment of soil for forest crops, nurseries and agricultural crops, sowing and planting of forests, agrotechnical and forestry care); forest protection work (spraying, pollination and aerosol processing of forest crops); forestry work (cutting in young animals, when thinning, passing and sanitary cutting, wood rubbing); Hydromeliorative and forest.drying work, the construction of roads (work on the preparation of tracks for a forest.vascular network, work on the installation of a forest.vascular network on a prepared highway); fire measures; Transport work.

The individual rate of consumption of fuel and lubricants is the rate of fuel consumption by a machine of a particular brand for the production of a unit of work (products) or per unit of working time, in relation to certain conditions of production of work.

The fuel consumption for the operation of the machines is not included: the fuel consumption for the overhaul of the machines (including the delivery of the car and back to the consumer, testing and running in the overhaul components of the machine, the car is after the overhaul before putting it before putting it fuel loss during storage and transportation of oil products and other repair and economic needs not related to the implementation of the technological process directly.

Fuel costs are not included in the norms of fuel consumption caused by deviation from the adopted technology, violation of the operating mode, non.compliance with the requirements for the quality of the supplied fuel and other irrational costs.

In addition, in the norm of fuel consumption, tractors do not include fuel costs for moving from the parking lot to the place of work at the beginning and end of the shift, as well as moving from the site to the site during the shift exceeding, in total, 10 km.

In cases where local fuel consumption standards of standard standards given in this collection operating in separate farms, current local norms should be preserved.

Instructions for the application of the consumption standards of fuel and lubricants

The norms of fuel consumption by mechanisms on mechanized works performed in forestry are mainly designed in weight units (kg) per unit of work performed (ha, km).

If it is necessary to translate the consumption rates of fuel and fuel and lubricants into volumetric units (liters), the following ratio should be used:

Y. fuel density, kg/l (for diesel fuel. 0.825, for gasoline. 0.74).

Determination of the density of petroleum products (fuel, oils) and the density of the actual temperature is carried out according to GOST 3900-85 “Oil and oil products. Determining methods ”and is made using the oil.diagram (arreometer).

Below is the density of liquid fuel and lubricating oils at 20 ° C.

Table 1. The density of automobile and diesel fuel and lubricating oils at 20 ° C

Fuel consumption given in regulatory tables is set for summer operating conditions of tractor units at an air temperature of 20 ° C and above. At an average ambient temperature below 20 ° C, the flow rate should be multiplied by the temperature coefficient K = 1.01.

The norms for the consumption of lubricating oils for maintenance of tractors are accepted in a % attitude to the spent diesel fuel at the norm and are given in table 2.

table 2. Follow oil costs for tractors maintenance

The rate of lubricating oils in % to the spent fuel (by weight)

Industrial, spindle and others. Special purpose oils

The consumption rate of automobile gasoline for starting engines is 1.5% of the consumption of diesel fuel according to the norm.

The consumption rates of combustible materials for cutting are compiled for the third category of the height of the cut.out part of the tree (height above sea level. up to 500 m).

Fuel consumption rates during forested works are designed for optimal compositions and operating modes of tractor units for areas with a slope of up to 5 °, located in plain conditions, with a height above sea level up to 500 m.

The unit processes only tractor.overtime, from the point of view of security, areas (up to 12 °), relief elements over 12 ° trap.

For work performed on the slopes of beams and ravines, fuel consumption rates are set using the factors. The amendments are given in table 3.

Table 3. Coefficients of correction of the effect of the relief on fuel consumption

Correct coefficient for fuel consumption, depending on the angle of the slope, hail.

When the tractor units on rocky soil are operating, fuel consumption for appropriate work should be increased taking into account the correction factors for soil stony. The correction factors are given in table 4.

Table 4. The coefficient of soil stony amendments

In the case of typical standards of fuel consumption by tractor units when working in mountain conditions, the standards given in tables should be adjusted to the height of the terrain above sea level (table 5).

Table 5. Coefficients of amendments to a height above sea level

For soils with varying degrees of humidity, the fuel consumption rate should be calculated using correction factors (table 6).

Table 6. Correct coefficient for soil moisture

Fuel and lubricants’ consumption rates are given for areas with a temperate climate.

When operating machines in other climatic zones, the winter fuel consumption rate is adjusted (table 7).

The main problems with oil supply

When the chainsaw is operating, two types of problems with the supply of lubrication to the chain can be observed:

  • Insufficient oil flow that can be caused for various reasons. If you do not take measures in time, the quality of work will noticeably deteriorate, and the chain itself may completely become unusable.
  • Excess amount of oil. In this case, after long work, puddles of grease can accumulate under the saw. This not only affects the flow of oil, which will have to be constantly added, but also negatively affects the ecology.

Both of these problems must be eliminated as soon as possible after their detection. This will extend the service life and reduce the consumption of lubricant fluid.

In what proportions to mix oil and gasoline for chainsaws?

The chainsaw is equipped with a single.cylinder two.stroke engine, which uses the fuel mixture to work. For refueling, you will need 92nd gasoline and special oil for two-stroke aero-cooled engines.

We prepare the mixture in the proportion of oil and gasoline. 1:40. In other words, we observe the ratio of 1 liter of gasoline. 25 grams of oil. Most often, such a volume is contained in a standard cap of container with technical fluid.

Mix the mixture well in a separate container. Owners Fubag FPS 56 were lucky, because it is already in the kit. At the end of the preparation of the fuel mixture, pour it into the gas tank.

What oil for chainsaws to choose? For our engines, we recommend Fubag 2T Extra semi.synthetic oil. optimally selected quality composition. We pay attention to the fact that oil for four.stroke engines or for boat engines will not work in any way.

The fuel mixture for the chainsaw is not the only thing where the oil is used. The devices have another technological tank where the lubricant is poured for the chain. By the time of fuel production, oil for the chain also ends, so it will be necessary to add it every time after refueling the tool.

Which oil to choose for lubrication of the chain? We recommend special branded Fubag Super Chain chain oil.

Test. checking the supply of fuel mixture

Our saw is refuel. Launch the engine and test the oil supply.

one. Check the lids of the gas tank and the oil tank. They must be tightly closed. 2. This model has a light starting system and a primer. a fuel pump button. Stretch the handle of the air damper and turn on the ignition toggle switch.

Pull a hand starter. Important! The saw should not be in the hands, only on the ground! This is necessary in order not to get injured when jerking.

four. We give the engine to work for 30-40 seconds at idle, after which the air damper can be transferred to its original position.

I drank ready for work, click the launch levers. This model is equipped with an anti.vibration system, which significantly reduces the load on the operator. To stop the saw, just release the start button. The chain will stop, the engine needs to be held for several minutes at idle. After that, translate the ignition to the position of.

Test. checking chain oil

They figured out the engine. Now let’s evaluate the correctness of the supply of chain oil.

To do this, after starting the engine, drive the circuit at medium speed to remove excess oil. If necessary, we adjust the feed using a screwdriver. You need to insert it from the bottom of the coupling and set the desired oil consumption.

Selecting a suitable lubrication of electric saws

When choosing oil, you need to consider the following:

  • Applying motor oil is permissible only on the recommendation of the manufacturer. This information is in the instructions.
  • Better to buy special oils. In this case, the material should have high adhesive parameters.
  • Do not use too cheap oils. They will harm the instrument.
  • Do not use spent engine oil. It contains a lot of pollution.

It is recommended to buy substances for lubricating the tool only in specialized stores. Such funds are of high quality and give the desired effect. When buying material on the market or at random points, there is a risk of colliding with a fake. It can lead to a tool breakdown.

Attention! If you use grease not according to the instructions, the manufacturer may refuse to service and guarantee.

Repair and malfunctions

Stihl 180, although famous for high reliability and quality, is still breaking. As they say, engineers are powerless against two things: fools and time. Therefore, over time, any owner will face some kind of malfunction in the saw that will require repairs. Based on our experience, we collected the most popular and wrote one general article about the malfunctions of STIHL saw and their repair, as well as detailed articles on the following topics:

Below in the text, in the right places, we also refer to articles about adjusting the carburetor and replacing the piston group.

When carrying out repair work, you will need to know how to disassemble and assemble a stihl chainsaw.


That is why the operation of the chainsaw should be paid to the fact that the saopan is not polluted. Very often, in the manufacture of the structure, a primer is installed. Due to this, the start of the engine is greatly simplified.

The design features of such an element determine that the fuel enters the carburetor in advance. The requirements for the fuel used are the first question that arises when using a chainsaw is the choice of the most suitable fuel. Experts recommend carefully choosing gasoline for the chainsaw, since with a poor.quality substance, the construction of the internal combustion engine can be damaged.

If you are faced with the purpose that the Stihl-180 chainsaw is not started. then if you figure it out, you will understand that the tool from a cool state will start without effort.

When purchasing and refueling a new device, a fairly large number of different factors should be taken into account. An example can be called that a gentle mode is selected at the initial stage of starting a chainsaw. The following points can be attributed to other features:

  • The tool is seasoned with a mixture, which contains 20% more oil. A higher concentration can lead to the fact that the composition will not completely burn. Therefore, the dosage should be carried out with high accuracy.
  • Playing time is indicated by the manufacturer in the operating instructions.

As practice shows, only 3-5 gas station refueling is enough for a full-fledged driving tool, after which it can be used for full work. Some foreign modern models no longer need to run.in. However, it is not recommended to use them immediately at high load.

Types of oil

Two.stroke oil is a separate lubricant for internal combustion engines. These lubricants differ from the rest of their properties. As already noted, special requirements are imposed on two.stroke oils.

For gasoline 2-stroke oil engines, the following qualities must have the following qualities.

  • The minimum amount of ash and coke, which are formed in the cylinder during combustion. Lubrication, in an ideal case, should completely burn out.
  • It should easily and completely dissolve in fuel.
  • Lubrication material must have lubricant, anti.symbolic, protective properties at elevated temperatures. And it should also protect well against corrosion.

If the lubricant system is separate, then it is necessary that the oil remains fluid and pumps well. If we take into account the scope of use and the specifics of 2-stroke engines that serve as engines for scooters and mopeds, engines on lawn mowers, boat engines and others, then separate requirements are also for the toxicity of the material.

If the lubricant falls on the soil, then for the environment it should be as safe as possible, and if it enters the water, it should decompose very quickly.

Such oils must comply with TC-W3 and 2 T standards. Very often from analogues they can be distinguished by color, as they are additionally painted. Basically they have blue. Even when mixing with gasoline, it is clearly visible.

According to the standard 2 tons, such lubricants are used in engines with air cooling from lawn mowers and chainsaws and ending with motorcycles (light). But for use in suspended motors with water cooling and jet ski, TC-W3 standard oils are calculated.

There are low oil oils for winter operation. Lubricants can have the following basis:

Recommendations and customs advice

You may notice that in the modern market there is a large range of oils for boat and other 2-stroke engines. You can also find ready.made products in which the oil is already diluted and ready for use. To do this, it is poured into the canister to the combustible, mixed well and poured into the tank of technology.

In terms of properties and price, products can be very different. Synthetic oil is more expensive than mineral. It is because of this that difficulties arise when buying. It is worth noting that first of all it is necessary to focus when choosing the information indicated by the engine manufacturer.

If it is said that it should be poured into the technique of the TC-W3 standard, then any that complies with this standard is suitable. In this case, it does not play a role that it is synthetics or mineral water. You need to choose brands with a good reputation and beware of fakes.

If the instructions for use are spelled out separately recommendations on oils, then it is strictly forbidden to pour other types of lubricants.

The thing is that initially the engine is designed only to work with the specified material, and if you begin to use other lubricants, this will quickly lead to the release of the unit from the working condition. Simple equipment, especially produced in the USSR, can successfully work on MS-20. But the imported motor can be closed and stop working in a few hours.

It is strictly forbidden to pour two.stroke diesel or automobile gasoline oils into the engines, and even more so, “working out”. There are a large number of additives in such lubricants, when combustible, they form a lot of ash. It is worth considering that if you ignore all these rules, then not only imported, but also domestic technique, which differs in its endurance, will soon break down.

Application in practice

From all of the above, it is worth noting that you need to choose a two.stroke oil responsibly. The main task before pouring a lubricant into the motor is to study the instructions for operating. If the manufacturer allows you to use various oil, then you can fill in a mineral water or more expensive synthetics.

Before infusion, make sure that the lubricant complies with the recommended standards. In practice, the difference between synthetics and mineral water will be insignificant. But still, on synthetics, the motor can start a little better, and wear less at high speeds. In the combustion chamber can be less than a car and coke.

But if the instructions indicate that it is worth pouring only a certain synthetics, then in no case should a mineral water be used, even if it is the same standard. In such a situation, on a number of important parameters, mineral oil is still not suitable. And all due to the fact that the lubricant system of the engine for the use of oils with the mineral base is not designed.

Is it possible to 92 gasoline instead of 76 (80)?

An interesting topic, I asked about why manufacturers use additives and do not immediately produce gasoline with the right very. And here’s what I dug up: ”Different technologies are used to obtain high.octane gasoline from oil, but only one of them. catalytic reforming. allows you to immediately get the necessary octane numbers. up to 99. But this is expensive: the share of such gasoline in the total balance of high.octane fuels does not reach 50%. The rest are produced according to less complex technologies such as catalytic cracking or hydrocracking: for them octane numbers. 82–85. And the simplest and cheapest are straight.Russian gasolines, but their octane numbers rarely exceed 50-60 units.

This is where various octan-sedimentary additives and additives arise. They can be divided into three groups. The first is based on the use of metal.containing additives. a memorable tetraethylsvin, who gave the world ethyl gasoline, now almost everywhere prohibited. The additive was extremely cheap and terribly effective. in general, the dream of an oilman. True, vile carcinogens flew out of the exhaust tube Now it has been replaced by much less dangerous Ferrotzen.

The main problem of such additives is the formation of raids and deposits in the combustion chamber, on candles, as well as in catalysts and on working surfaces of engine control sensors. The limit level of ferrocene is normalized. 0.017%, but who follows this? There are additives on the basis of Nickel, manganese, but the problems are the same.

Another group of highly octane additives works on the principle of “mixed” increase in the octane number: basic gasoline is mixed with something very, very stable. Most often used monomethylalinin (MMna), whose octane number is already 280. These gasolines are more expensive than ferrocene, but the main obstacle to their distribution is the norms of Euro III and Euro IV, limiting the level of “aromatics”.

The third, most advanced group. ethers and alcohols. In this case, everything is in order with ecology, but there are problems. Firstly, a relatively low octane number is about 120, so there are quite a lot of them-sometimes even more than 10%. Since the ethers have significantly lower heat.intensive ability than basic gasoline, the “calorie content” of fuel falls. Secondly, the broadcasts are aggressive in relation to rubber, paint, some plastics. It was the aggressiveness of the broadcasts that required a normative restriction of their consonated gasolines, in the production of “etheric” the cheaper and, therefore, the most common.
